In this fanfiction, perhaps Hiruzen realizes Naruto's potential much earlier and decides to train him privately. He might take Naruto on secret missions to build his experience and confidence. This would not only strengthen Naruto's skills but also their bond, which could have a huge impact on the village's future.
In the fanfic, Hiruzen could train Naruto in stealth and intelligence - gathering techniques. Naruto is often portrayed as a straightforward fighter in the original series. But with Hiruzen's training, he could become a more well - rounded ninja. He might learn how to infiltrate enemy bases, gather crucial information, and use that knowledge to outwit his opponents. This would add a new dimension to Naruto's character and his abilities in battles.
In a fanfiction where Naruto is trained by Hiruzen, Naruto would likely have a more traditional and disciplined training. Hiruzen could instill in Naruto the values and ethics of being a true shinobi from the very beginning. Since Hiruzen has seen many great shinobi in his time, he could mold Naruto into a shinobi similar to those of the past. This might mean Naruto would be more proficient in basic ninja skills like stealth and intelligence gathering. Also, his chakra control could be improved more rapidly under Hiruzen's guidance, which would enhance his overall combat capabilities.
In a 'naruto adopted by hiruzen fanfiction', the plot could involve Naruto having a closer bond with the older generation of shinobi. Hiruzen would surely introduce Naruto to his trusted comrades. Naruto could learn unique jutsu from them. Also, his growth as a ninja would be different. Instead of seeking attention through pranks, he might focus more on living up to Hiruzen's name. His relationship with Sasuke could also be affected. Maybe they would become rivals in a more positive way, with Naruto having a stronger sense of family and purpose because of Hiruzen's influence.
Perhaps Hiruzen is being influenced by some dark force or a hidden group within the village. They convince him that Naruto, with the Nine - Tails inside him, is too dangerous to be left unchecked. So, Hiruzen, in a moment of weakness, decides to betray Naruto. He could secretly arrange for Naruto to be sent on dangerous missions alone with the intention of getting him killed. Naruto, being oblivious to this at first, later realizes what's going on and has to fight not only against external enemies but also against the betrayal of his own village leader.
The plot might involve Naruto learning about the history and politics of the village from Hiruzen. Since Hiruzen has a wealth of knowledge and experience, he could be guiding Naruto on how to be a great leader in the future, not just a powerful ninja.
Well, it could be about Hiruzen teaching Naruto all kinds of ninja skills from a young age. Maybe he also imparts wisdom and values to Naruto, which makes Naruto grow into a very different ninja compared to the original story. For example, Naruto might be more composed and less of a troublemaker in the village at first because of Hiruzen's strict yet loving upbringing.
One possible plot is that Hiruzen discovers a plot against Naruto by some anti - Uzumaki forces. He then uses his combat skills and his network of spies to stop the threat before it reaches Naruto. He might also place some of his most trusted shinobi to guard Naruto at all times.
The main characters would be Naruto and Hiruzen. However, we might also see characters like Kakashi make an appearance. Kakashi could be a bit jealous at first that Hiruzen is taking Naruto under his wing, but then he might see the benefits and offer his own advice to Naruto on the side.
Naruto's character might become more solemn. Hiruzen's influence could make him less of a prankster. He'd be more focused on his training and responsibilities as a ninja.
Well, it could be about Naruto being forced into a dark situation where he has to train for killing. Maybe he's been misled or there's a great threat that makes him think this is the only way. For example, he might be tricked by an enemy who disguises as a friend and convinces him that the only way to protect the village is to become a killer.
